Une unité de classification (39) classifie les informations de récupération extraites par l'unité d'extraction (38) en fonction du code d'échec indiqué par les premières informations. Pour chaque groupe classé par l'unité de classification (39), l'unité de classification (40) classifie les informations de récupération incluses dans le groupe selon les mesures indiquées par les troisièmes informations. Une unité de réglage (41) règle la priorité pour chaque groupe classé par l'unité de classification (40).
